The　rapid　recombination　of　photogenerated　carriers　and　strong　photocorrosion　have　considerably　limited　the　practical　application　of　CdS　in　the　field　of　photocatalysis.　Loading　a　cocatalyst　has　been　widely　utilized　to　largely　enhance　photocatalytic　activity.　In　the　present　work,　a　WC@C　cocatalyst　was　prepared　by　a　novel　molten　salt　method　and　explored　as　an　efficient　noble-metal-free　cocatalyst　to　significantly　enhance　the　photocatalytic　hydrogen　evolution　rate　of　CdS　nanorods.　The　WC@C/CdS　composite　photocatalyst　with　a　7　wt%　content　of　WC@C　showed　the　highest　photocatalytic　hydrogen　evolution　rate　of　8.84　mmol　g(-1)　h(-1),　which　was　about　21　and　31　times　higher　than　those　of　CdS　and　7　wt%　Pt/CdS　under　visible　light　irradiation.　A　high　apparent　quantum　efficiency　(AQY)　of　55.28%　could　be　achieved　under　420　nm　monochromatic　light.　Furthermore,　the　photocatalytic　activity　of　the　7　wt%　WC@C/CdS　photocatalyst　exhibited　good　stability　for　12　consecutive　cycles　of　the　photocatalytic　experiment　with　a　total　reaction　time　of　42　h.　The　excellent　photocatalytic　performance　of　the　photocatalyst　was　attributed　to　the　formation　of　a　Schottky　junction　and　the　loading　cocatalyst,　which　not　only　accelerated　the　separation　of　the　photogenerated　carrier　but　also　provided　a　reactive　site　for　hydrogen　evolution.　This　work　revealed　that　WC@C　could　act　as　an　excellent　cocatalyst　for　enhancing　the　photocatalytic　activity　of　CdS　nanorods.
